Mirroring & Remote Mirroring Configuration

Mirroring is a feature for switched port analyzer. The administrator can use the Mirroring to debug

network problems. The selected traffic can be mirrored or copied on a destination port where a

network analyzer can be attached to analyze the network traffic.

Remote Mirroring is an extend function of Mirroring. It can extend the destination port to another

switch, so the administrator can analyze the network traffic on the other switches.

If you want to get the tagged mirrored traffic, you have to set VLAN egress tagging as Tag All on the

reflector port. On the other hand, if you want to get untagged mirrored traffic, you have to set VLAN

egress tagging as Untag ALL on the reflector port.

Setting Description

Mode To enable/disable the mirror or Remote Mirroring function.

Type

Select switch type.

 Mirror: The switch is running on mirror mode. The source port(s) and

destination port are located on this switch.

 Source: The switch is a source node for monitor flow. The source port(s),

reflector port, and intermediate port(s) are located on this switch.

 Intermediate: The switch is a forwarding node for monitor flow and the

switch is an option node. The object is to forward traffic from source

switch to destination switch. The intermediate ports are located on this

switch.

 Destination: The switch is an end node for monitor flow. The destination

port(s) and intermediate port(s) are located on this switch.

VLAN ID

The VLAN ID points out where the monitor packet will copy to. The default

VLAN ID is

200.

Reflector Port

The reflector port is a method to redirect the traffic to Remote Mirroring VLAN.

Any device connected to a port set as a reflector port loses connectivity until the

Remote Mirroring is disabled.

In the stacking mode, you need to select switch ID to select the correct device. If

you shut down a port, it cannot be a candidate for a reflector port.

If you shut down the port which is a reflector port, the remote mirror function

cannot work.

Note1: The reflector port needs to select only on Source switch type.

Note2: The reflector port needs to disable MAC Table learning and STP.

Note3:

The reflector port only supports on pure copper ports.
